Metric BMI Calculator
You are underweight. BMI <18.5
Being underweight can damage your health and can contribute to a weakened immune system, fragile bones, fertility problems and a lack of energy.
There might be an underlying medical cause for your low weight, such as an overactive thyroid. Or you may simply be underweight because your diet isn't providing you with enough energy (calories). Stress or other emotional problems can sometimes cause a change in eating patterns. See your GP for help and advice.
Please contact your Local GP surgery for support.
